Sun damage is an incredibly broad description of any number of skin changes that are the result of photodamage from the sun. When sunlight hits your unprotected skin, it can damage healthy cells. Over time, this damage builds up and begins to cause noticeable changes in the skin. These changes can include wrinkles, age spots, loose skin, and hyperpigmentation. The following are treatments that can help with all of these things, though prevention by using broad spectrum SPF daily and avoiding prolonged sun exposure will always be best.
